Review on 🌡️ Klein Tools 69140 K-Type Thermometer: Accurate HVAC Pipe Temperature Clamp, Measures -4 to +212°F by Juan Castillo

I bought this for my small multimeter. I have a lease where I started doing HVAC maintenance myself. For the rest of my life I couldn't understand why the temperature on the suction side rose as I charged more refrigerant into the system. I finally decided to test the sensor that came with the multimeter and ended up using it to attach the original temperature sensor to the HVAC line to get accurate readings. It was at least 15 degrees. I really wanted and expected it to work. However, I just couldn't figure out how to get it to work. He comes back. BYW, you need to pay the shipping when you return this item.
